0190/0900 dialer program on his computer has dialed a premium rate number with every
connection, resulting in dramatically increased costs.
We recommend that you ask your telephone provider to block this number range directly
for immediate protection against undesired dialers (0190/0900 dialers).
Your Avira product can detect the familiar dialers by default.
If the option Dialers is enabled with a check mark in the configuration under Threat
categories, you receive a corresponding alert if a dialer is detected. You can now simply
delete the potentially unwanted 0190/0900 dialer. However, if it is a wanted dial-up
program, you can declare it an exceptional file and this file is then no longer scanned in
future.
Double Extension Files
Executable files that hide their real file extension in a suspicious way. This camouflage
method is often used by malware.
Your Avira product recognizes "Double Extension Files". If the option Double Extension
files is enabled with a check mark in the configuration under Threat categories, you
receive a corresponding alert if your Avira product detects such files.

Your Avira product detects scareware. If the option Fraudulent software is enabled with a
check mark in the configuration Threat categories, you receive a corresponding alert if
your Avira product detects such files.

the lunch hour). Nevertheless, with the wealth of games downloadable from the Internet, a
fair bit of mine sweeping and Patience playing goes on among company employees and
civil servants. You can download a whole array of games via the Internet. Email games
have also become more popular: numerous variants are circulating, ranging from simple
chess to "fleet exercises" (including torpedo combats): The corresponding moves are sent
to partners via email programs, who answer them.
Studies have shown that the number of working hours devoted to computer games has
